摘要
介绍了CCD信号采集电路的设计过程,该设计由单片机产生CCD内部垂直移位寄存器工作所需的转移脉冲,并由TMS320LF2407A芯片产生CCD水平移位脉冲和复位脉冲,然后在CCD输出信号之后设计了模数转换和数据存储电路,再由DSP和单片机共同控制DSP和数据存储FIFO之间的数据读取,从而可以实现DSP对CCD信号的处理,最终实现对目标的测量。
The design process of CCD signal acquisition circuit is introduced, in which the shift pulse that the CCD internal vertical shifting register requires is produced by MCU, and the CCD level shift pulse and reset pulse are produced by TMS320LF2407A chip. The circuit of analog to digital conversion and data storage is designed after the CCD output signal, and the data transmission between DSP and FIFO is controlled by the DSP and MCU. So that the processing of CCD signal is realized and the objective is measured.
